A general approach is reported to fabricate a series of single‐phase 2:17‐type rare‐earth cobalt (RE2Co17, RE = Y, Ce, Pr, Nd, and Gd) nanoalloys by precisely controlled calcium thermic reduction of amorphous RE‐Co precursors. High‐purity hexagonal RE2Co17 phases are formed without the precipitation...
